Try split top fin a different way.
Make two tails....move them away from each other like the F-14.....may be F-22 raptor Make sure they are forward swept like the eagles tail.
Then tilt em 5 to 10 degrees off of the vertical. Not 35 or 40degrees like you did...
I wanna see how it looks .
Basically a Bigger Eagle with Twin tails....that slight move away from each other as they move away from fusalage...
